CloudFlare known bots List
How does Firewall Rules handle traffic from known bots?
Caution about potentially blocking bots
When you create a Firewall rule with a Block, Challenge (Captcha), or JS Challenge action, you might unintentionally block traffic from known bots. Specifically, this might affect search engine optimization (SEO) and website monitoring when trying to enforce a mitigation action based on URI, path, host, ASN, or country.
See How do I create an exception to exclude certain requests from being blocked or challenged?
